Giants lose Kieschnick on waivers to D-backs

LOS ANGELES -- Outfielder Roger Kieschnick's tenure with the Giants organization ended Friday, when he was claimed off waivers by the Arizona Diamondbacks and sent to Triple-A Reno.

Kieschnick, 27, hit .202 in 38 games for the Giants last year, his fifth in the organization after being selected in the third round of the 2008 First-Year Player Draft. He showed power in the Minor Leagues, hitting 71 homers. But Kieschnick couldn't duplicate that trait in his limited appearances with the Giants, recording a .226 slugging percentage in 84 at-bats.

This spring, Kieschnick was eclipsed by Juan Perez in the competition for a reserve outfield spot.

"There's always mixed emotions," assistant general manager Bobby Evans said. "You like to keep a guy, but there's an opportunity to stay on a 40-man roster and maybe get a 25-man spot. We want to see our guys do well. That's good for him. We're sorry that our roster got to where it got and it forced us to make a tough decision with him."

Pagan excels at coming through in late innings

LOS ANGELES -- Statistics illustrate just how productive Giants center fielder Angel Pagan has been in clutch situations.

Since the start of the 2013 season, Pagan entered Friday batting .370 (20-for-54) with three home runs in the eighth inning or later, compared to .260 for the rest of the Giants in those situations. Despite playing only 71 games last year, Pagan collected three walk-off hits, the most by a Giant since Andres Torres also had three in 2010.

Pagan says little about his hitting approach, which may reflect his ability to keep things simple.

"In those situations, I just want to have good at-bats," he said.

Evidence of Pagan's value since he joined the club in 2012 has continued to mount. According to ESPN Stats & Information, the Giants are 129-99 (.566) when Pagan has played. In his absence, they are 44-56 (.440).

Posey's jersey among most popular with fans

LOS ANGELES -- Buster Posey's jersey ranks seventh on the list of Major League uniform tops purchased most by fans.

The Giants catcher was eclipsed only by David Ortiz and Dustin Pedroia of the Red Sox, Derek Jeter of the Yankees, Yadier Molina of the Cardinals, Clayton Kershaw of the Dodgers and Andrew McCutchen of the Pirates.

The list, released jointly by Major League Baseball and the MLB Players Association, is based on sales of Majestic jerseys from MLB.com/Shop, the official online shop of Major League Baseball, since the 2013 World Series concluded.

Posey led these rankings in mid-2013, coming off his National League Most Valuable Player season and the Giants' World Series triumph.

Plenty on tap for Giants' first homestand

LOS ANGELES -- Giveaways and special events will fill the Giants' opening homestand, which encompasses a trio of three-game series against Arizona, Colorado and Los Angeles.

The first 40,000 fans through the gates Tuesday will receive Opening Day calendars. Starting time that afternoon is scheduled for 1:35 p.m. PT, with pregame festivities set to begin at 12:45 p.m.

That's followed by Hunter Pence bobblehead night Wednesday and a "Farewell to the 'Stick" observance Thursday, featuring appearances by various Giants and 49ers -- including Roger Craig, the former manager, and Roger Craig, the ex-running back. Fans purchasing tickets to different special events will receive Candlestick Park replicas or long-sleeved Croix de Candlestick T-shirts. The first 20,000 fans will receive a Farewell to the 'Stick scarf.

Promotions next weekend include Fireworks Night on Friday and a sports bag giveaway Saturday.

The start of the Dodgers series coincides with Jackie Robinson Day, April 15. A portion of proceeds from each special-event ticket sold will benefit the Jackie Robinson Foundation. The next night, the first 20,000 fans will receive 2014 Giants magnet schedules.
